Cancelling the error

Cancelling the error

When the frequency counter reaches the value 0, the error is cancelled and so are the parameters associated with it.

The immediate cancelling of the entire errors memory takes place in the following cases:

• by means of the "cancel errors memory" command sent by the tester;
• by interrupting the supply to the injectors control unit (disconnecting the battery or the connector for the control unit).

Fault diagnosis with the Fiat/Lancia Tester

On the right hand side of the engine compartment (near the engine oil dip stick) is the diagnostic socket to which the Fiat/Lancia Tester is connected.

The exchange of data between the control unit and the Tester takes place via a two direction serial line (line K) using the standard Bosch communication protocol.

The Tester can supply the following information:

• display of the errors;
• display of engine parameters;
• active diagnosis.
